DETAILED DESCRIPTION

In the following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of various exemplary embodiments or implementations of theinvention. As used herein “embodiments” and “implementations” areinterchangeable words that are non-limiting examples of devices ormethods employing one or more of the inventive concepts disclosedherein. It is apparent, however, that various exemplary embodiments maybe practiced without these specific details or with one or moreequivalent arrangements. In other instances, well-known structures anddevices are illustrated in block diagram form in order to avoidunnecessarily obscuring various exemplary embodiments. Further, variousexemplary embodiments may be different, but do not have to be exclusive.For example, specific shapes, configurations, and characteristics of anexemplary embodiment may be used or implemented in another exemplaryembodiment without departing from the inventive concepts.

Unless otherwise specified, the illustrated exemplary embodiments are tobe understood as providing exemplary features of varying detail of someways in which the inventive concepts may be implemented in practice.Therefore, unless otherwise specified, the features, components,modules, layers, films, panels, regions, and/or aspects, etc.(hereinafter individually or collectively referred to as “elements”), ofthe various embodiments may be otherwise combined, separated,interchanged, and/or rearranged without departing from the inventiveconcepts.

The use of cross-hatching and/or shading in the accompanying drawings isgenerally provided to clarify boundaries between adjacent elements. Assuch, neither the presence nor the absence of cross-hatching or shadingconveys or indicates any preference or requirement for particularmaterials, material properties, dimensions, proportions, commonalitiesbetween illustrated elements, and/or any other characteristic,attribute, property, etc., of the elements, unless specified. Further,in the accompanying drawings, the size and relative sizes of elementsmay be exaggerated for clarity and/or descriptive purposes. When anexemplary embodiment may be implemented differently, a specific processorder may be performed differently from the described order. Forexample, two consecutively described processes may be performedsubstantially at the same time or performed in an order opposite to thedescribed order. Also, like reference numerals denote like elements.

The DR1-axis, the DR2-axis, and the DR3-axis are not limited to threeaxes of a rectangular coordinate system, such as the x, y, and z - axes,and may be interpreted in a broader sense. For example, the DR1-axis,the DR2-axis, and the DR3-axis may be perpendicular to one another, ormay represent different directions that are not perpendicular to oneanother. Additional axes such as Dra and DRb may be added to thecartesian coordinates and have properties similar to the axes DR1, DR2,and DR3.

Spatially relative terms, such as “beneath,” “below,” “under,” “lower,”“above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), andthe like, may be used herein for descriptive purposes, and, thereby, todescribe one elements relationship to another element(s) as illustratedin the drawings. Spatially relative terms are intended to encompassdifferent orientations of an apparatus in use, operation, and/ormanufacture in addition to the orientation depicted in the drawings. Forexample, if the apparatus in the drawings is turned over, elementsdescribed as “below” or “beneath” other elements or features would thenbe oriented “above” the other elements or features. Thus, the exemplaryterm “below” can encompass both an orientation of above and below.Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90degrees or at other orientations), and, as such, the spatially relativedescriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particularembodiments and is not intended to be limiting. As used herein, thesingular forms, “a,” “an,” and “the” are intended to include the pluralforms as well, unless the context clearly indicates otherwise. It isalso noted that, as used herein, the terms “substantially,” “about,” andother similar terms, are used as terms of approximation and not as termsof degree, and, as such, are utilized to account for inherent deviationsin measured, calculated, and/or provided values that would be recognizedby one of ordinary skill in the art.

Various exemplary embodiments are described herein with reference tosectional and/or exploded illustrations that are schematic illustrationsof idealized exemplary embodiments and/or intermediate structures. Assuch, variations from the shapes of the illustrations as a result, forexample, of manufacturing techniques and/or tolerances, are to beexpected. Thus, exemplary embodiments disclosed herein should notnecessarily be construed as limited to the particular illustrated shapesof regions, but are to include deviations in shapes that result from,for instance, manufacturing. In this manner, regions illustrated in thedrawings may be schematic in nature and the shapes of these regions maynot reflect actual shapes of regions of a device and, as such, are notnecessarily intended to be limiting.

In this specification, when an element (or a region, a layer, a portion,or the like) is referred to as “being on”, “being connected to”, or“being coupled to” another element, it may be directlydisposed/connected/coupled to another element, or an intervening thirdelement may also be disposed therebetween.

Like numbers refer to like elements throughout. Also, in the drawings,the thicknesses, ratios, and dimensions of the elements are exaggeratedfor effective description of the technical contents. “And/or” includesone or more combinations which may be defined by the associatedelements.

It will be understood that, although the terms first, second, etc. maybe used herein to describe various elements, these elements should notbe limited by these terms. These terms are only used to distinguish oneelement from another element. For example, a first element may bereferred to as a second element, and similarly, a second element may bereferred to as a first element without departing from the scope of theinventive concepts. The singular forms are intended to include theplural forms as well unless the context clearly indicates otherwise.

It will be understood that the terms “includes” or “comprises”, whenused in this specification, specify the presence of stated features,integers, steps, operations, elements, components, or a combinationthereof, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components, orcombinations thereof.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which the inventive concepts belong. Itwill be further understood that terms, such as those defined in commonlyused dictionaries, should be interpreted as having a meaning that isconsistent with their meaning in the context of the relevant art andwill not be interpreted in an idealized or overly formal sense unlessexpressly so defined herein.

Referring to FIG. 8 , an input sensor 400 includes an active area AA anda non-active area NAA. The active area AA overlaps the display area DR(see FIG. 3 ) of the display panel 300 (see FIG. 3 ), and the non-activearea NAA overlaps the non-display area NDR (see FIG. 3 ). The activearea AA may include a central area CTA positioned at the center andperipheral areas CNA disposed outward from the central area CTA. Thecentral areas CTA may refer to substantially center areas of each sideof the active area AA. Here, the central area CTA may be all areasexcept for the peripheral areas CNA within the active area AA. Theperipheral areas CNA are areas corresponding to edge portions (corners)of the input sensor 400 in a plan view and may be areas in a thirddirection DRa and a fourth direction DRb. Here, the third direction DRaand the fourth direction DRb are diagonal directions between a firstdirection DR1 and a second direction DR2. The central area CTA may be anarea corresponding to a central portion of the input sensor 400surrounded by the peripheral areas CNA in a plan view.

In an embodiment, the input sensor 400 may include a plurality ofelectrodes. The plurality of electrodes may include a plurality of firstelectrodes S1 and a plurality of second electrodes S2. The plurality ofsecond electrodes S2 may be disposed corresponding to the plurality offirst electrodes S1. For example, referring to FIGS. 6 and 7 , threesecond electrodes S2 may be disposed corresponding to one firstelectrode S1.

In an embodiment, the electrodes of at least one of the first electrodesS1 or the second electrodes S2 may include center electrodes CTEdisposed in the central area CTA and peripheral electrodes CNE disposedin the peripheral areas CNA. FIG. 8 illustrates that the secondelectrodes S2 include the center electrodes CTE and the peripheralelectrodes CNE, but the embodiment of the inventive concept is notlimited thereto. Likewise, the first electrodes S1 may also include thecenter electrodes CTE and the peripheral electrodes CNE (see FIG. 10 ).

The input sensor 400 may include a plurality of first signal lines SL1and a plurality of second signal lines SL2. The plurality of firstsignal lines SL1 may be connected to the plurality of first electrodesS1. The plurality of second signal lines SL2 may be connected to theplurality of second electrodes S2. In an embodiment, the first signallines SL1 may include signal lines from a first first signal line SL1-1to a n-th first signal line SL1-n. For example, the first signal linesSL1 may include a first first signal line SL1-1 and a second firstsignal line SL1-2 which are connected to a first sensor block SB1 and asecond sensor block SB2, respectively. The first signal lines SL1 andthe second signal lines SL2 may be connected to sensing patterns of thefirst electrodes S1 and sensing patterns of the second electrodes S2,respectively.

In the embodiment, the second signal lines SL2 may connect the secondelectrodes S2. FIG. 8 illustrates one first electrode S1 and threesecond electrodes S2 corresponding to the one first electrode S1. Theconfiguration described above is one embodiment, and one first electrodeS1 may be disposed corresponding to n second electrodes S2. Also, theembodiment of the inventive concept is not limited to the configurationsdescribed above, and the first electrode S1 corresponding to theplurality of second electrodes S2 may be provided in plurality. In FIG.8 , a first second signal line SL2-1 may connect a third secondelectrode S2-3 (see FIG. 7 ) of the first sensor block SB1 to a firstsecond electrode S2-1 of the second sensor block SB2.

FIG. 9 is an enlarged plan view illustrating center electrodes accordingto an embodiment of the inventive concept. FIG. 10 is an enlarged planview illustrating a portion of a peripheral area according to anembodiment of the inventive concept. Hereinafter, center electrodes CTEand peripheral electrodes CNE will be described with reference to FIGS.9 and 10 .

FIG. 9 is an enlarged view of a region AA' of FIG. 8 of a sensor blockSB. Referring to FIG. 9 , the center electrodes CTE may include sensingpatterns SP and the floating patterns FP. Here, each of the sensingpatterns SP may be a sensing part configured to sense a touch input of auser. Each of the floating patterns FP is a portion in which the sensingpattern SP is not disposed, and may be a dummy electrode portion in astate floating from the sensing pattern SP. The sensing pattern SP andthe floating pattern FP may include a mesh shape. The mesh shape of thesensing pattern SP and the floating pattern FP will be described withreference to FIG. 11A. The floating pattern FP may be disposed toaddress a visibility limitation when the input sensor 400 is seen fromthe outside. The floating pattern FP may be provided in plurality. InFIG. 9 , the first electrode S1 and the second electrode S2 are disposedin the central area CTA and thus may correspond to the center electrodesCTE. A center electrode CTE of FIG. 9 is not adjacent to the peripheralelectrode CNE (see FIG. 8 ) and thus may include second centerelectrodes CTE2. A ground area GDA may be defined between the firstelectrode S1 and the second electrode S2. The ground area GDA may makethe first electrode S1 and the second electrode S2 spaced apart fromeach other.

The floating pattern FP may be in a floating state as not to beconnected to the sensing pattern SP. Unlike the center electrode CTE, aperipheral electrode CNE (see FIG. 10 ) does not include a floatingpattern FP and may include substantially only a sensing pattern SP.

FIG. 10 is an enlarged view of BB' of FIG. 8 including sensor blocks,the active area AA and the non-active area NAA spanning the central areaCTA and peripheral area CNA. Referring to FIG. 10 , a surface area ofperipheral electrodes CNE may be less than a surface area of centerelectrodes CTE. A peripheral electrode CNE is disposed in a peripheralarea CNA within an active area AA of the input sensor 400 and thus has asurface area less than that of a center electrode CTE due to a limitedspace. Thus, a surface area occupied by the sensing pattern of theperipheral electrode CNE is also less than that of the center electrodeCTE. Embodiments of the inventive concepts are provided to improvesensitivity of the peripheral electrode CNE which is low for the abovereason including the limited space thereof.

In the embodiment, the peripheral electrode CNE does not include thefloating pattern FP. That is, analogous portions of the peripheralelectrode CNE, which are occupied by the floating pattern FP in thecenter electrode CTE, do not including the floating pattern FP. That is,a surface area ratio of the sensing pattern SP area to the total area ofthe peripheral electrode CNE not having floating patterns FP may begreater than a surface area ratio of the sensing pattern SP area to thetotal area of the center electrode CTE having floating patterns.

In an embodiment, the peripheral electrode CNE may include a firstperipheral electrode CNE1 and a second peripheral electrode CNE2. Thesecond peripheral electrode CNE2 may be disposed further inside theinput sensor 400 than the first peripheral electrode CNE1 in a firstdirection DR1. Each of the first peripheral electrode CNE1 and thesecond peripheral electrode CNE2 may have a round edge EZ. Curvature ofthe round edge of the first peripheral electrode CNE1 may be greaterthan curvature of the round edge of the second peripheral electrodeCNE2. Particularly, the first peripheral electrode CNE1 may be disposedin a portion of the peripheral area CNA closest to the corner, and thesecond peripheral electrode CNE2 may be disposed closer to the centerelectrode CTE within the peripheral area CNA than is the firstperipheral electrode CNE1. In this specification, an edge of an area mayrepresent a border portion of the area. In an embodiment, the edge EZ ofthe active area AA may be a border of the active area AA. That is, theedge EZ of the active area AA may be a boundary portion between theactive area AA and the non-active area NAA.

In an embodiment, a length LH1 of a first peripheral electrode CNE1 in asecond direction DR2 may be greater than a length LH2 of the secondperipheral electrode CNE2 in the second direction DR2. The seconddirection DR2 is a direction crossing the first direction DR1. In theembodiment, the first peripheral electrode CNE1 has a larger loss ofsurface area due to a round edge with large curvature than does thesecond peripheral electrode CNE2, and thus, the surface area of thesensing pattern of the first peripheral electrode CNE1 is increased byextending the length in the second direction DR2. Accordingly, thesensitivity in the peripheral area CNA may be improved.

In an embodiment, the center electrodes CTE may include a first centerelectrode CTE1 and a second center electrode CTE2. The first centerelectrode CTE1 may be disposed adjacent to the first peripheralelectrode CNE1 and/or the second peripheral electrode CNE2. The secondcenter electrode CTE2 may be disposed apart from the first peripheralelectrode CNE1 and/or the second peripheral electrode CNE2.

In an embodiment, the surface area occupied by the floating pattern FPin the first center electrode CTE1 may be less than the surface areaoccupied by the floating pattern FP in the second center electrode CTE2.That is, floating patterns FP are removed from portions of the firstcenter electrode CTE1 that are in contact with the first and secondperipheral electrodes CNE1 and CNE2. Thus, the first center electrodeCTE1 has a smaller number of floating patterns FP and larger surfacearea occupied by sensing patterns than the second center electrode CTE2.

In an embodiment, the active area AA may be divided into a first areaAA1 and a second area AA2. The first area AA1, as an area occupying mostof the active area AA, can represent the area up to the edge EZ of theactive area AA. The second area AA2 may protrude from the edge EZ to thenon-active area NAA and overlap the non-display area NDR (see FIG. 3 )of the display panel 300 (see FIG. 3 ) in a plan view.

The first peripheral electrodes CNE1 may include first portions CNE1-P1disposed in the first area AA1 and second portions CNE1-P2 disposed inthe second area AA2. The input sensor 400 may include dummy patterns DMPwhich are disposed in the non-active area NAA and adjacent to the edgesEZ of the second peripheral electrodes CNE2. In the embodiment, thefirst peripheral electrode CNE1 includes a round edge EZ having a largecurvature, and thus, there may be a loss of surface area of the sensingpattern when compared to other electrodes. Thus, to compensate the lossof surface area, the first peripheral electrode CNE1 does not have adummy pattern DMP unlike the second peripheral electrode CNE2, andinstead includes the second portion CNE1-P2 in a position where thedummy pattern DMP is to be positioned. Thus, the surface area of thesensing pattern may be enlarged.

FIG. 11A is an enlarged plan view illustrating a mesh shape according toan embodiment of the inventive concept. FIG. 11B is an enlarged planview illustrating a portion of an peripheral area according to anembodiment of the inventive concept. FIG. 11A is an enlarged view of XX'of FIG. 10 , and FIG. 11B is an enlarged view of YY' of FIG. 10 .

FIG. 11A illustrates each of second center electrodes CTE2 of the centerelectrodes CTE (see FIG. 8 ), which is apart from the peripheralelectrodes CNE. In FIG. 11A, a mesh shape of a sensing pattern SP and afloating pattern FP of the second center electrode CTE2 and a mesh shapeof a ground pattern GP illustrate a representative configuration of meshshapes applied to a plurality of electrodes in the active area AA of thedisplay apparatus according to an embodiment of the inventive concept.The ground pattern GP may be disposed in a ground area GDA and may bepatterns having a mesh shape floating from the sensing pattern SP.

Referring to FIG. 11A, the center electrodes CTE2 may include sensingpatterns SP and a floating patterns FP. The sensing patterns SP may havea mesh shape and the floating pattern FP may have a double-helix shape.The ground pattern GP may also have a mesh shape. In FIG. 11A, the twosecond center electrodes CTE2 may be separated from each other by aboundary portion 10. The boundary portion 10 may separate secondelectrodes, corresponding to a first electrode, from each other. Theboundary portion 10 may be a cut portion of the sensing pattern SP. Thesensing pattern SP in one of the second center electrodes CTE2 and theother of the second center electrodes CTE2 may be cut in the boundaryportion 10. Taking into consideration the sensitivity of the sensingpattern SP, the boundary portion 10 may have a zigzag shape. Breaks BRare disposed in several places of the enlarged view XX' to illustratewhere the sensing patterns SP are separated from the floating patternsFP.

The floating pattern FP may float from the sensing pattern SP. A shapeof the floating pattern FP is not limited to the shape illustrated inthe drawings. A cut portion 20 of the floating pattern FP may have azigzag shape to minimize a reduction in sensitivity of the sensingpattern SP.

Referring to FIG. 11B, each of a first electrode S1 and a secondelectrode S2 may include a first peripheral electrode CNE1. Each of thefirst peripheral electrodes CNE1 may include a first portion CNE1-P1 anda second portion CNE1-P2. The second portion CNE1-P2 may be a portionprotruding from an edge EZ of an active area AA to a non-active areaNAA.

FIG. 11B, each of the first portion CNE1-P1 and the second portionCNE1-P2 of the first peripheral electrode CNE1 may have a mesh shape.

FIG. 12 is an enlarged plan view illustrating a portion of a peripheralarea according to an embodiment of the inventive concept. FIG. 13 is anenlarged plan view illustrating signal lines of a peripheral areaaccording to an embodiment of the inventive concept. FIG. 14 is anenlarged plan view illustrating signal lines of a central area accordingto an embodiment of the inventive concept.

FIG. 12 is an enlarged view of CC' of FIG. 8 . FIG. 13 is an enlargedview of DD' of FIG. 12 , and FIG. 14 is an enlarged view of EE' of FIG.12 . When describing with reference to FIG. 12 , descriptionsoverlapping with those in FIGS. 8 and 10 will be omitted.

In an embodiment, referring to FIGS. 13 and 14 , the first signal linesSL1 (see FIG. 8 ) and the second signal lines SL2 (see FIG. 8 ) of anembodiment of the inventive concept may have a straight line shape or amesh shape within an active area AA. In FIG. 13 , for the first signallines and the second signal lines, first signal lines SL11 and secondsignal lines SL21 at least connected to the peripheral electrodes CNEmay have a straight line shape within the active area AA. In FIG. 14 ,for the first signal lines and the second signal lines, first signallines SL13 and second signal lines SL23 connected to the centerelectrodes CTE may have a double-helix shape within the active area AA.The double-helix shape described herein may also be referred to as afigure-8 shape.

The signal lines of at least one of the first signal lines SL11 and thesecond signal lines SL21 connected to the peripheral electrodes CNE mayhave a straight line shape in the active area AA as well as in thenon-active area NAA. The signal lines of at least one of the firstsignal lines SL13 and the second signal lines SL23 connected to thecenter electrodes CTE may have a straight line shape in the non-activearea NAA, but may have a double-helix shape in the active area AA.

In FIGS. 13 and 14 , signal lines are illustrated in different mannersto compare the shape of signal lines of the peripheral area CNA and theshape of signal lines of the central area CTA. In another embodiment,unlike that illustrated in FIG. 14 , the first and second signal linesSL13 and SL23 connected to the center electrode CTE of the central areaCTA may also have a straight line shape within the active area AA.

That is, all of the signal lines disposed within the input sensor 400(see FIG. 8 ) may have a straight line shape within the active area AA.Accordingly, the surface area occupied by the signal lines within theactive area may be reduced, and the surface area occupied by theelectrodes may be increased.

In a plan view, the surface area occupied by the first signal lines SL11and/or the second signal lines SL21 having the second signal line shapeis less than the surface area occupied by the first signal lines SL13and/or the second signal lines SL23 having the double-helix shape. Forexample, a width WH1 of an area within the active area AA in a firstdirection DR1, which is occupied by the straight line-shaped secondsignal lines SL21 connected to the peripheral electrodes CNE, may beless than a width WH2 of an area within the active area AA in the firstdirection DR1, which is occupied by the double-helix -shaped secondsignal lines SL23 connected to the peripheral electrodes CNE.

In the embodiment of the inventive concept, the first and/or secondsignal lines SL11 and SL21 connected to the peripheral electrodes CNE ofthe peripheral area CNA have the straight line shape, and thus, thesurface area occupied by the first and/or second signal lines SL11 andSL21 within the active area AA may be reduced. That is, with respect tothe peripheral electrodes CNE, the surface area of the peripheralelectrodes CNE connected to the first and second signal lines SL11 andSL21 having the straight line shape is greater than the surface area ofthe peripheral electrodes CNE connected to the first and second signallines SL13 and SL23 having the double-helix shape.

In FIG. 13 , the first signal lines SL11 of the first signal lines SL1(see FIG. 8 ), which are connected to the peripheral electrodes CNE, mayextend in the non-active area NAA while being spaced at least about 15um from the peripheral electrode CNE. In the embodiment, the surfacearea of the sensing pattern in the first peripheral electrode CNE1 maybe increased by reducing a spaced distance WT1 to the signal linesconnected to the first peripheral electrode CNE1. That is, the firstperipheral electrode CNE1 may be expanded such that the sensing patternis adjacent to the first and second signal lines SL11 and SL21 by acertain distance. In the embodiment, each of the first peripheralelectrodes CNE1 may include a first portion CNE1-P1 and a second portionCNE1-P2. The second portion CNE1-P2 may be a portion which extends fromthe first portion CNE1-P1 and protrudes to the non-active area NAA. Thesecond portion CNE1-P2 may be at least about 15 um from the first andsecond signal lines SL11 and SL21. The spaced distance WT1 between thesecond portion CNE1-P2 and the first and second signal lines SL11 andSL21 may be less than a spaced distance WT2 between an edge EZ of theactive area AA and the first and second signal lines SL11 and SL21. Forexample, the spaced distance WT1 between the first and second signallines SL11 and SL21, which are connected to the first peripheralelectrodes CNE1 and disposed within the non-active area NAA, and thefirst peripheral electrodes CNE1 may be at least about 15 um to about 20um. In the embodiment, by using an empty space formed such that thefirst peripheral electrode CNE1 and the signal lines connected to thefirst peripheral electrode CNE1 are spaced apart from each other, thesurface area of the sensing pattern of the first peripheral electrodeCNE1 may be increased, and the sensitivity in the peripheral area CNA ofthe input sensor 400 may be enhanced.

As described above, the inventive concepts according to an embodimentmay provide the display apparatus in which the electrodes disposed inthe peripheral areas of the input sensor have the improved sensitivity.
